This is a tough one. For some reason, if I start debugging GDB, it
doesn't reach the handle_sigint line. However, with fprintf there, I'm
seeing output. Could I be doing something wrong or is this expected?

I configured && compiled like this:
  cvs -d '' co gdb
  CFLAGS=-g ../src/configure

I was wondering if any of the -W compile options stop me from debuging
GDB in this case.
